What is the primary purpose of an auxiliary low-water cut-off device?

The primary purpose of an auxiliary low-water cut-off device is to ensure sufficient water level in a boiler or other water-containing systems. This device serves a crucial function by monitoring the water level within the system and automatically shutting off the burner or energy source if the water level drops below a safe threshold. Maintaining an adequate water level is essential for the proper operation of a boiler, as insufficient water can lead to overheating, potential damage to the boiler, and even hazardous conditions such as explosions.

By ensuring that a sufficient water level is maintained, this device helps protect the integrity of the boiler and promotes safe operation, thereby preventing failures that could result from low water conditions. Understanding this function highlights the importance of auxiliary safety devices in managing boiler operation and ensuring safety standards are met in various piping and heating systems.
